IP cameras for long distances?

Question

CCTV

hello, ip poe cameras are connected at a distance of 600 meters via utp 5e cable, every 80-100 meters there are poe switches, there are 12 cameras in total, among them 4mp and 8mp. the registrar of such switches is 100 Mbps in total 5 pieces, the problem is that the connection disappears with the cameras and appears every 5-10 minutes, everyone is lost in turn and reappears, what is the problem? advised to use gigabit switches, if the problem is in them where to put them? at the end in the middle?

Your cameras completely clog the bandwidth of 100 Mbps of the switch, the bandwidth of your registrar is 160 Mbps, which also seems to be not enough for your cameras.
Cable 5e with a length of 100 meters will also not be enough, it is better to replace it with category 6.
It seems that everything except the cameras is under replacement.
An indiscreet question: who drafted the project, at whose expense will the "banquet" be?
PS It turns out that you need to remove the router and sequentially recline the cameras, starting from the one closest to the registrar, until you achieve stable operation. (Or discard all cameras, except for the last, farthest one, and add one at a time) Then draw conclusions: whether to change the nearby switches to gigabit ones, whether to change the wires to category 6, whether to change the registrar, ...

1. On the register, find the service menu with the network card loading. Check the bitrate, turn off MJPEG on the cameras and switch the second stream to h264. Check if this reg model has a limit on incoming and outgoing bitrate - 160 Mbps.
2. Switch models for the studio, not every switch assembled by Uncle Liao works normally in the long garland mode.
3. For lengths over 50m, the cable should be laid half a meter from the power ones, be copper ftp with AWG 24. Laying on metal structures is also contraindicated. And in a human way - a star is cooked on 4 fiber optics.
